Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging box lamination technology, and in particular to a lamination mechanism for an automated packaging box processing line. Background Technology
[0002] Lamination is a process that uses a transparent plastic film to be applied to the surface of a packaging box through hot pressing technology. This process aims to protect the product and increase its gloss. In the packaging industry, this process is used for common packaging products such as cartons and boxes.
[0003] However, in the existing technology, although it can adapt to the film covering requirements of packaging boxes of different sizes, when using a hot cutter to cut the excess film on both sides and try to make it tightly adhere to the surface of the packaging box, there is often a lack of effective means to further press the upper and lower films together. This results in the upper and lower films not being fully bonded or unable to achieve a tight fit with the surface of the packaging box during the cutting operation. Utility Model Content
[0004] The purpose of this utility model is to provide a film-coating mechanism for an automated packaging box processing line in order to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-4This utility model provides a technical solution: a laminating mechanism for an automated packaging box processing line, comprising a top plate 1, a column 2, a middle plate 3, a hot cutting blade frame 15, and a laminating assembly. The middle plate 3 is fixedly connected to the four sides of the column 2, and the top plate 1 is fixedly connected to the top of the column 2. A second guide rod 17 passing through the top plate 1 is fixedly connected to the four sides of the top side of the hot cutting blade frame 15. A second cylinder 18 is fixedly installed on the top plate 1. A tension spring 16 is sleeved on the second guide rod 17, and the two ends of the tension spring 16 are fixedly connected to the top plate 1 and the hot cutting blade frame 15, respectively. A groove 1501 is opened on the top of the hot cutting blade frame 15, and the output end of the second cylinder 18 contacts the groove 1501. The second cylinder 18 drives the hot cutting blade frame 15 along... When the second guide rod 17 moves downward, the tension spring 16 provides a certain buffer and additional pressure during this process to ensure that the hot cutting frame 15 can evenly press the film. When the output end of the second cylinder 18 retracts, the tension spring 16 pulls the hot cutting frame 15 back to the initial position. The middle plate 3 has a hot cutting groove 301 in the middle. L-shaped support plates 19 covering the hot cutting groove 301 are slidably installed on both sides of the bottom of the hot cutting groove 301. The film coating assembly is arranged between the hot cutting frame 15 and the hot cutting groove 301. The bottom of the middle plate 3 is fixedly connected to a fixing block 20 arranged outside the hot cutting groove 301. The bottom of the fixing block 20 is fixedly connected to a limit frame 5. A conveyor belt 4 adapted to it is arranged below the limit frame 5. Specifically, the packaging box to be coated is placed on the film on the hot cutting groove 301. The output end of the second cylinder 18 descends and pushes the hot cutting blade frame 15 downward along the second guide rod 17, pressing the upper film, packaging box, and lower film evenly onto the closed L-shaped support plate 19. While completing the heat sealing, the excess film is cut off. Because the upper and lower films are squeezed and deformed and pressed tightly onto the packaging box, it is ensured that the upper and lower films are closely attached to the upper and lower surfaces of the packaging box. After heat sealing and cutting, the second cylinder 18 drives the hot cutting blade frame 15 to rise back to the initial position, opens the L-shaped support plate 19, and the coated packaging box is accurately placed on the conveyor belt 4 under the guidance of the limit frame 5. The coated packaging box is sent to the next process or collection point. This device achieves efficient and high-quality coating effect by precisely controlling the action of the second cylinder 18, the temperature of the hot cutting blade frame 15, and the coordination between the components, while ensuring good adhesion and appearance quality between the film and the packaging box.
[0030] Specifically, such as Figure 1-4As shown, the film coating assembly includes an upper film take-up roller 10, a lower film take-up roller 9, an upper film release roller 14, a lower film release roller 13, a belt 11, and a geared motor 12. The upper film release roller 14 and the lower film release roller 13 provide the required plastic film. The free ends of the plastic film are respectively fixed on the corresponding upper film take-up roller 10 and lower film take-up roller 9. The upper film release roller 14 and the upper film take-up roller 10 are rotatably mounted on the two side columns 2. The lower film take-up roller 9 and the lower film release roller 13 are rotatably mounted on both sides of the middle plate 3. The belt 11 is connected between the upper film take-up roller 10 and the lower film take-up roller 9. The geared motor 12, which is connected to the lower film take-up roller 9, is fixedly mounted on the column 2. Specifically, the geared motor 12 drives the lower take-up roller 9 to rotate, and the upper take-up roller 10 is linked by the belt 11, so that the upper and lower films can move forward synchronously and cover the surface of the packaging box. Through the precise control and coordinated operation of the film coating component, a high-efficiency and high-quality film coating effect is achieved, which not only improves the protective performance of the product, but also enhances the aesthetic appearance, while ensuring the consistency of production efficiency and product quality.
[0031] Specifically, such as Figure 3 and Figure 4 As shown, the horizontal end of the L-shaped support plate 19 passes through the gap between the top of the fixing block 20 and the limiting frame 5. A fixing plate 6 is fixedly connected to the column 2, and a first cylinder 8 is fixedly installed on the fixing plate 6. The output end of the first cylinder 8 is fixedly connected to the vertical end of the L-shaped support plate 19. First guide rods 7 passing through the fixing plate 6 are fixedly connected to both sides of the vertical end of the L-shaped support plate 19. Specifically, during the lamination process, when the packaging box is placed above the heat sealing groove 301, the first cylinders 8 on both sides start synchronously, pushing the L-shaped support plate 19 to move relative to each other until the bottom of the heat sealing groove 301 closes, providing support for the packaging box during lamination. The use of the heat sealing groove ensures that the packaging box will not deform or shift during heat sealing and cutting. After lamination, the first cylinders 8 on both sides pull the L-shaped support plate 19 to move in opposite directions to open the heat sealing groove 301, allowing the laminationd packaging box to be unloaded onto the conveyor belt 4.
[0032] Working principle: During use, the packaging box to be coated is placed on the film on the hot cutting groove 301. The output end of the second cylinder 18 descends and pushes the hot cutting blade frame 15 to move downward along the second guide rod 17, pressing the upper film, packaging box and lower film evenly on the closed L-shaped support plate 19. While completing the heat sealing, the excess film is cut off. After the heat sealing and cutting are completed, the second cylinder 18 drives the hot cutting blade frame 15 to rise back to the initial position. At the same time, the first cylinders 8 on both sides pull the L-shaped support plate 19 to move in opposite directions to open the heat sealing groove 301, so that the coated package falls accurately on the conveyor belt 4 under the guidance of the limit frame 5, and the coated packaging box is sent to the next process or collection point.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
